Morcegos da Chapada do Araripe, nordeste do Brasil

Abstract

Chapada do Araripe is a plateau located within the Caatinga biome in northeastern

Bats (Mammalia, Chiroptera) from the Nísia Floresta National Forest, with new records for the state of Rio Grande do Norte, northeastern Brazil

“…Bats from the family Phyllostomidae corresponded to the largest number of captures, which is in accordance with most inventories in the Neotropics (e.g. Bernard et al 2001, Esbérard et al 2006, Novaes & Laurindo 2014). This pattern is related both to the high abundance of phyllostomid bats in Brazilian tropical areas and to the selectivity of the mist-netting method, which tends to capture bats that forage near the ground and vegetation (such as fruit-eating and nectar-feeding bats).…”

“…Our record is a new marginal point of occurrence and extends the distribution of the species by about 470 km southeast (from Russo-CE) and about 210 km north (from São Lourenço da Mata-PE) (Moratelli & Wilson 2013). In northeastern Brazil, this species occurs mainly in xeric forests and shrublands within the Caatinga biome (Novaes & Laurindo 2014, Novaes et al 2015, Silva et al 2015; this is the second peripheral record of M. lavali in the adjacent Atlantic Forest, besides a specimen captured in a seasonal lowland forest area near the coast of Pernambuco (Moratelli & Wilson 2013). The high number of captures in the NFNF suggests these bats often forage at low heights near to the ground and forest edges.…”

“…The record of P. discolor in the state of Rio Grande do Norte was expected, since it occurs in the neighboring states of Ceará (Fabián 2008) and Paraíba (Feijó & Langguth 2011). In northeastern Brazil, this species occurs in moist and dry forests in Caatinga (Souza et al 2004, Novaes & Laurindo 2014 and Atlantic Forest biomes (Mikalauskas 2005, Faria et al 2006.…”

Bats of Alagoa Grande, a semi-arid area of Northeastern Brazil

“…Among these species, Peropteryx macrotis, Cynomops planirostris and Noctilio leporinus had between 1 and 4 individuals captured by ground level mist-nets in other studies (Gregorin et al, 2008;Novaes and Laurindo, 2014;Rios et al, 2008;Sá-Neto and Marinho-Filho, 2013;Silva et al, 2004). This result could be related to the inefficiency of the chosen sampling method to capture insectivorous species.…”

“…Novaes and Laurindo (2014) recorded 24 species to Chapada do Araripe in the states of Ceará and Pernambuco employing a comparable amount of mist-net hours. Sá-Neto and Marinho-Filho (2013) recorded 31 species to middle São Francisco River in the Bahia state with 7.6 times the sampling effort used herein.…”
